write excel report with charts from powercli for multiple vcenters

Supports vsphere 4.1 & 5.1 with Excel 2010.

Was just a bit of fun to get my head into powercli and trying to use the get-view as much as possible to speed things up.

I look after eight environments with 1000+ guests and constantly get asked for reports, very frustrating with 8 vcenter servers.

### There is nothing in this code that will cause any damage, only using get-view ###

Can a moderator pehaps check and confirm to ease people's minds?

Q. I am not happy with the top if statements, I want it to if null then goto function {blah} but cannot get my head around it.

It works as is but just not as streamlined as I would like it.

Once I have that I will clean it up and put some order to it, but would appreciate any feedback and recommendations.

The final aim is to push to html rather than excel.
